DIEGO COSTA ensured Arsene Wenger's 22-year reign as Arsenal manager will end in Huddersfield and not Lyon as the former Chelsea man hit the winner for Atletico Madrid in a closely fought Europa League semi-final. See how the action unfolded with Express Sport.

Atletico Madrid striker Diego Costa haunted Arsenal again by firing his side to a 1-0 win in tonight’s Europa League semi-final second leg to send the Spaniards into the final and deny Arsene Wenger a dream end to his long reign as Arsenal coach.

Atletico won the tie 2-1 on aggregate and will meet either Salzburg or Marseille in the final in Lyon on May 16.

Costa proved a handful for Arsenal when he played for Chelsea and the Spain striker broke the deadlock in a tight, tense game at the Wanda Metropolitano, striking in first-half stoppage-time after being played in by Antoine Griezmann.

Arsenal defender Laurent Koscielny was carried off on a stretcher early in the first half with a suspected torn Achilles tendon and they struggled to cope with Costa's power and the flair of his attacking partner Griezmann.

Wenger's side were blunt in attack against a typically determined and resilient Atletico defence and they only had one shot on target, a distance strike from Granit Xhaka which was not enough to beat goalkeeper Jan Oblak.

Atletico did not create many chances but they always looked in control and kept a remarkable 12th consecutive clean sheet in all competitions at their Wanda Metropolitano stadium to reach a fifth European final since 2010.

“There was character there but the mistakes, which have haunted them all season, were in both games. Mistakes at the back, switched off.

“We talked about the education of the players, building blocks, and it wasn’t there. Bellerin tonight, he will be disappointed with what happened, it could have been averted.”

OUCH!

22:10: After progressing from their first six semi-final ties in European competition, Arsenal have now been eliminated in each of the last two (2008/09 vs Manchester United in the Champions League and this year vs Atletico Madrid).

TWITTER ROUND-UP

Uche: Arsenal can't say they were unlucky. They simply didn't do enough. Lacked the ruthlessness you need. And the individual errors which have killed this team over the years once again cost them. The players have let Arsene Wenger down. The change coming has to be significant.

Andrew: Dominate possession, carve out opportunities, spurn chance after chance. Same old Arsenal. In the next few years we will find out if that is an Arsenal trait or a Wenger-inspired characteristic.

Chris: The failure to put away chances & win games that are in our grasp like this week & last, shows everything we lack under Wenger and why it’s right for his era to come to an end.

FINAL COUNTDOWN

22:06: Atletico Madrid have reached their fifth European final in the last 9 seasons, their third in the Europa League which is a joint-record in the competition with Sevilla.

DON’T SHOOT!

22:05: Despite seeing 55 per cent possession, Arsenal mustered just one single shot on target tonight.

ATLETICO MADRID 1-0 ARSENAL

FT: Arsenal have been knocked out of the Europa League. Arsene Wenger will not end his 21-year reign with a trophy. Full reaction coming up.

That pesky Diego Costa ruins the fairytale ending.

92: Simeone wastes a bit more time by sending Savic on for Partey, who takes an eternity to leave the field. Mustafi is sent up front!

91: No! Koke with a terrible clearance and Arsenal keep the ball love. It’s sent wide to Monreal, who promptly knocks it straight out of play.

90: Nearly game, set and match as the ball breaks for Torres, who sees his firmly-struck effort parried away by Ospina.

Three minutes of added time. Arsene Wenger is stood motionless on the touchline.

89: Good game-management from the hosts, who get the ball and take it to the corner. Precious seconds ticking away.

87: So aggravating. Monreal and Bellerin have received the ball in wide positions so often tonight, but they’ve barely put a decent cross into the box. It’s throw the kitchen sink time!

REUTERS

Atletico Madrid vs Arsenal: Europa League score, news and updates

85: So Arsenal have five minutes plus stoppage time to score and force extra time. It’s worth remembering that Atletico Madrid haven’t conceded at home since January 20…

83: Vintage Diego Costa. He’s signalling to the bench that he wants to come off. The Atletico bench ignores his plea, so he decides to sit on the deck like a child.

Hilarious and infuriating in equal measure. Diego Simeone eventually gets the message and brings on Fernando Torres to replace him.

80: FIGHT, FIGHT, FIGHT! You knew Diego Costa couldn’t go an entire 90 minutes without a shoving match. He and Mustafi engage in a battle when the Spaniard withheld the ball. Storm in a teacup really, but both are booked.

77: For goodness sake. Monreal finds enough space to head a ball across the six-yard box but not a single Arsenal player attacks it. You’ve got to gamble now, lads!

74: Henrikh Mkhitaryan nearly writes himself into Arsenal history with a terrific strike that narrowly flies over Oblak’s crossbar. Arsenal are sensing an opportunity here…

REUTERS

72: Mkhitaryan replaces Wilshere. Wenger’s only other attacking options are Nketiah and Iwobi…

70: How?! Firstly I’m asking how on earth Antonio Conte thought it was a good idea to sell Diego Costa, and secondly I’m wondering how Atletico Madrid haven’t doubled their tally.

Costa leaves Chambers for dead with a Cruyff turn before teeing up Griezmann, whose shot is deflected into Ospina’s arms.

45: And we’re back underway folks. I’m afraid that it’s been conformed that Koscielny has torn his Achilles. No World Cup for the Frenchman.

Analysis from our reporter Matt Dunn, in Madrid.

HT: If Arsenal could have got to the sanctity of the dressing room for a half-time pep talk, who knows? But it is shocking how easily Arsenal’s defence can be ripped apart.

A poor header, a simple diagonal pass and Bellerin half asleep as Costa charged past him. Certainly the Arsenal defence Wenger inherited 22 years ago would not have let in a goal like that.

Koscielny’s horrific injury is, of course, a factor, but while Arsenal have shown some signs they could still hurt Atletico and pull this back, there are no guarantees that the Gunners defence won’t simply fall apart a second time.

TWITTER ROUND-UP

Uche: Just awful defending from Calum Chambers. Criminal that he didn't take the safe option and put the ball out of play. Instead he heads it straight to an Atletico player & 5secs later its a goal. Koscielny was similarly guilty last week of trying to play dangerous area. Woeful.

Matt: Well it turns out it is going to be poor defending that forms the large part of Arsene Wenger's footballing obituary. Undone by hopeless defensive tactics yet again. Now mission impossible.

Michael: How bad of a defender is Hector Bellerin? The problem with modern day full backs is that they are always out of position! No biggie for Arsenal though... they came here needing to score either way!

That’s the positive outlook I was after, Michael…

ATLETICO MADRID 1-0 ARSENAL

HT: A goal in first-half added time from Diego Costa has given the hosts a big, big advantage. Arsenal need an equaliser to force extra time, or two unanswered goals to win it.

ATLETICO MADRID 1-0 ARSENAL - COSTA

47: You just knew it would happen…

Diego Costa has come back to haunt Arsenal on the stroke of half time.

Monreal half-clears Oblak’s long punt forward but Partey collects and slips it to Griezmann. The Frenchman looks for options and sees that Costa has given Bellerin the slip with ease.

The former Chelsea striker holds Bellerin off with one arm and fires beyond Ospina.

45: Block! Gabi strides onto an attempted clearance and bangs one goalwards. Xhaka makes the block as we enter three minutes of stoppage time.

41: Atletico have flipped the switch. They’ve been on the front-foot for the last five minutes as Arsenal drop deeper and deeper.

REUTERS

39: Griezmann got glue on his foot? The Frenchman brings down a lofted free-kick with snow on it before spinning and firing inches wide of the post.

36: I don’t want to sound too surprised, but Arsenal have been very good. Composure, cohesion and everyone knows what they are supposed to be doing. Atletico getting frustrated.

33: Xhaka and Ospina have a communication breakdown. The ball is there for the goalkeeper to easily collect but Xhaka didn’t hear a call and thumped it out for a corner.

Partey thumps a thunderous 40-yard volley at goal but Godin is penalised for a totally unnecessary bodycheck on Mustafi.

30: Chance! That was a golden opportunity for Alexandre Lacazette to make the breakthrough. The Frenchman collects a throughball from Ozil but delays before being ushered away from goal.

He HAD to pull the trigger first time.

REUTERS

Atletico Madrid vs Arsenal: Europa League score, news and updates

28: “Shouldda gone down,” says every Tottenham supporter in the country. Chambers catches Costa inside the penalty area but the Spaniard stays on his feet and loses possession. I think referee Gianluca Rocchi would have given it.

26: Griezmann is very animated tonight. He’s just gestured at the crowd to make some noise and follows that by arguing with the referee for nothing. Pumped as they say…

23: Gabi sinfully loses the ball in midfield and Wilshere collects with glee. He lays it off for Bellerin, whose cross alludes everyone and bounces behind.

Bellerin and Monreal haven’t been scared to push forward tonight just need that final bit of quality.

20: Twenty minutes gone and Arsene Wenger will be fairly satisfied with what he’s seen. Atletico are dominating the ball but Arsenal look capable of scoring on the break with Lacazette, Welbeck and Ramsey linking up nicely.

18: I’ve just seen that If Arsenal do win the Europa League and Liverpool win the Champions League and finish fifth in the Premier League the team that finish fourth will miss out on the Champions League next season. Unlikely but how Gunners fans would enjoy doing that to Spurs…

REUTERS

15:Well we’re back underway and Callum Chambers is the man chosen to replace Laurent Koscielny. If ever there was a time to step up and become a hero, it’s now.

12:I might have been wrong about the knee injury folks. Koscielny been nursing an Achilles for more than a year, hope that's not as bad as it looks.

It’s a really worrying sight as he’s stretchered off the field. Both sets of supporters applaud Arsenal’s captain off the field.

10: Ouch! Koscielny is in agony. The Frenchman hits the deck with nobody around him. Must be a repeat of his troublesome knee injury. Not a chance he will continue as the stretchers are brought on.

9: He’s missed! Costa bullies Koscielny to win a long ball forward before shrugging Monreal off the ball like a school child. He plants it miles over the bar but that’s a worrying sign.

7: Chance! Great play from the Gunners with Lacazette whipping a dangerous cross across the six-yard box that Wilshere narrowly missed. The corner comes to nothing.

3: Well it didn’t take long for Arsenal to show their weakness at the back. Koscielny and Ospina collide when challenging for the same cross and the goalkeeper scrambles it clear.

1: And we’re underway at a packed Wanda Metropolitana folks. Must be 60,000 supporters in here and the atmosphere is ferocious. 3,700 Arsenal fans doing their best to make themselves heard.

Analysis from our reporter Matt Dunn, in Madrid.

20:03:Few minutes to go and the vast bowl of the Wanda Metropolitana is filling. The very modern public address system is blaring out but there is no need – it is noisy enough already. Atletico’s flag-waving ultras are in good voice down to the right of me as I sit high over the dugouts.

As with the first leg at Arsenal, we are having to endure another light show, however. Some of the lights are turned on. Others are turned off. It would perhaps be more impressive if there were not still bright blues skies above as the sun only just begins to set.

It is only when the music stops and the fans sing their club anthem that the hairs really begin to stand up on the back of the neck.

EEK…

20:02: We’re three minutes away from showtime folks. One thing I’m confused about though. Why is this young Atletico Madrid fan (presumably Spanish) holding a sign written in English to Fernando Torres?

Soyuncu, 21, is a talented centre-back who’s earned plaudits for his Bundesliga displays since joining from second-tier Turkish outfit Altinordu in 2016.

President Ozkan revealed that Bayern Munich were also vying for his signature but Arsenal have won the battle.

"Caglar Soyuncu set to join Arsenal," Ozkan confirmed at the International Football Economic Forum. "Arsenal demanded his youth information from us. We'll earn from him, if he joins Arsenal. Bayern Munich wants him too, but he's on the way to the Premier League."

NO DIEGO…

19:50: I’m afraid we won’t be seeing Atletico Madrid boss Diego Simeone marauding up and down the touchline tonight.

Simeone was dismissed from the dugout during last week's eventful first leg and will have to watch from the stands.

Who knows, he might even take a seat at some point.

TWITTER ROUND-UP

Jon: The fairy tale ending is Arsenal win and get to the final. The bitter sweet, realists' conclusion is Arsenal to grab a gutsy 0-0 draw, huffing and puffing but failing to blow Atletico's defence down. I'll plump for the former.

RM: Should have played the majority that started versus United. Way more threat and those players actually had desire.

Rez: I feel for our defence. Mavropanos should be partnering Koscielny. He handled Lukaku, whose physically similar to Costa, pretty well.

HOME COMFORTS

19:40: Yes, I’m aware of the irony of putting these posts back-to-back.

Diego Simeone's team have a formidable home record. The LaLiga outfit played their first game in their new home on September 16 and only Chelsea, Sevilla and Barcelona have departed with victories.

Arsenal need at least one goal to progress and even that could prove a challenge as Atletico are on an 11-game run of clean sheets at the Wanda Metropolitano.

TRAVEL SICK

19:38: Remarkably, Arsenal have only won seven away games all season across all competitions.

Even worse, Wenger's side have yet to take a Premier League point on the road in 2018. Their Europa League record stands up a little stronger, and an impressive 2-0 win at AC Milan earlier in the competition will give them hope of springing a surprise in the Spanish capital...

Analysis from our reporter Matt Dunn, in Madrid.

19:35:Arsene Wenger really only had one decision to make and has gone for Danny Welbeck ahead of fit-again Henrikh Mkhitaryan. Don’t think that’s a bad call as Welbeck has a knack of scoring goals when they are needed and goodness knows Arsenal need one.

Not since a gentleman of Girona, Portu to be precise, found the back of the net here on January 20 has an away side scored and that is just the first hurdle Arsenal need to cross.

They also have to keep the score down at the other end. And that is where Diego Costa comes in, back in the team to continue his torment of Arsenal from his days in a Chelsea shirt.

I actually fancy Arsenal to score. Koscielny and Mustafi to keep the door shut at the other end though? It will be a another nervy European night, for sure.

TWITTER ROUND-UP

Rez: If Arsenal need any motivation for scoring against a mean home defence they should look no further than Liverpool against Roma last night. Stats mean nothing.

Wish: If there was ever a time to deliver for Arsene Wenger this season, now would be that time. Let’s give him the BEST farewell by getting into the final!

Lewis: If Arsenal win Europa, I really can’t see Wenger handing over the reigns to a team that will be in the Champions League next season. Maybe a stipulation for a contract extension?

Please don’t open that box, Lewis!

CRAZY MONEY

19:25: Tickets for Arsene Wenger's final home match in charge of Arsenal are being sold for £1,800. No, that’s not a typo...

The Burnley clash on Sunday is a Category C fixture - the lowest of three tiers in Arsenal's official Premier League ticketing structure - with prices ranging from £26 to £38.50.

The club's website crashed in the moments after Wenger announced he would be leaving last month as Arsenal fans scurried to buy the final remaining tickets for the historic match.

But supporters without a ticket now face having to spend well over the odds to see the 68-year-old Frenchman's last home game.

Ticketbis, a secondary ticketing online market, claims to have a range of seats available from £143 to a staggering £1,800.

BIG IMPACT

19:20: Big Impact obviously being the sequel to Deep Impact, only smaller and far worse if you can imagine such a thing.

I digress. What I’m trying to say is that Arsene Wenger believes the difference between winning the Europa League or not will have a huge impact on the club’s future.

Asked if the game was one of the most important in his time at the club, Wenger replied: "The next one is always the most important in life.

"Of course it is the most important because it is the next one, because it is a big game as well. It influences the future of my club and that is why it is massive.

"It is a very, very big for us because the future of Arsenal Football Club is not exactly the same if we qualify for the Champions League or not."

19:05: This should be nice and quick. Arsene Wenger names the same starting XI who drew with Atletico Madrid at the Emirates Stadium last week.

There have been a few eyebrows raised at Wenger’s decision to start Danny Welbeck ahead of Henrikh Mkhitaryan, but I suppose it’s a fitness issue.

ATLETICO MADRID vs ARSENAL

19:00: Wait no longer folks, the line-ups have arrived. Well, the Atletico Madrid starting XI has at least. As you can see Diego Simeone has made three changes from the first leg with big bad Diego Costa starting in attack.

The Arsenal side has now arrived. No changes from the first leg but Henrikh Mkhitaryan is on the bench. Full team news on the way.

Who could replace Arsene Wenger at Arsenal? (Latest odds according to Betfair)

Arsenal have no fresh injury concerns ahead of the second leg of their Europa League semi-final against Atletico Madrid.

The Gunners headed to Spain with the tie finely poised at 1-1 but have the boost of a fit Henrikh Mkhitaryan, who returned from a knee injury at the weekend having sat out the first leg.

Alex Iwobi has travelled despite suffering a slight hamstring injury in the weekend defeat at Manchester United but Pierre-Emerick Aubameyang is cup-tied and Mohamed Elneny (ankle) and Santi Cazorla (Achilles) are also out.

Arsenal vs Atletico Madrid is being shown live on BT Sport 2, with the pre-match build-up starting at 7.00pm.
